Sulfadiazine: Effect on E. coli Infections in Mice.

Summary

1. In vitro tests show that sulfadiazine has slightly more bacteriostatic action on E. coli communis than sulfathiazole in 10 mg % concentrations. 2. In vivo experiments show that, with comparable blood levels, sulfadiazine is more effective than sulfathiazole in treating E. coli communis infections in mice.
